Another justification is rather indirect. Following the arguments in
Theory of Nothing (also mostly available in "Why Occams Razor" and "On
the Importance of the Observer in Science"), a number of really curly
philosophical problems melt away in a blaze of understanding. I refer
here to 

1) Occams Razor
2) The problem of Induction
3) Why anything bothers to exist
4) The Hilbert space structure of QM

Of course its not all plain sailing - the problem of the Occam
catastrophe means that the Anthropic Principle is rather mysterious,
rather than trivially obvious as it is in naive realist theories.

However solving 4 unsolvable mysteries in exchange for having another
one is not a bad deal, and is a pretty good justification for taking
these theories seriously.
